ARIES X55X User Manual

Series X55X Universal Zero Insertion
Force DIP Test Socket

FEATURES

• Aries’ Universal Test Socket accepts devices on 0.300 to 0.600 [7.62 to 15.24]
centers.

• All pin count sockets go into PCB with either 0.300 or 0.600 [7.62 to 15.24] centers.

• Contacts are normally closed to eliminate dependence on plastic to sustain contact.

• Socket handle can be configured with closed contacts (on) when in the UP or DOWN
position, and can be mounted on either the right or left side.

• Sockets can be soldered into PCBs or plugged into any socket. Socket fits into Aries’
or any competitive test socket receptacle.
